It doesn't work at all! How do I pair it with my system? My manual says I have to train it by pressing the program key, but I don't think it was installed.

Please help. Thanks!
Remote#1 - If the other button(s) work fine, the problem could be the specific switch you're pressing. The switch used (microswitch) is similar to the ones used in computer mice. These things go bad all the time and the only way around it is to have it replaced. Spend a few bucks on a new switch (most electronics shops have them) and several minutes with a soldering iron and that should bring it back to shape.

If either buttons work intermittently, it could be that the battery is loose or there is corrosion on the contacts.

Remote#2 - You either need to reprogram it or try the battery from Remote#1.
